DAVID WEINBERG, or ROCKAWAY BEACH, NE Y RK, AssIeNoR To PARAMOUNT ROOF FLANGE CORPORATION, A CORPORATION or NEW YORK.

ADJUSTABLE ROOF FLANGE.

Application filed May 13, 1927. Serial NO. 191,098.

The present-invention relates to improvemerits in adjustable roof flanges adapted for sealing the joint between the roof and SOll or other pipes passing therethrough.

It has for its object to provide a unitary device which may be quickly and easily applied to roofs of different pitches and re quiring no more than the tappmgof its collar or ring member into contact with the pipe to secure an effective leak-proof seal.

., In the carrying out of my invention it has been my particular aim to provide a new article of manufacture embodying a roof flange of suitable metal in which an orifice of proper size is formed and-a collar which is composed of ductile material, such as lead, having an interlocking water-tight connection with the flange, this collar being preferably molded with certain beads which 1mpart the necessary strength and rigidity to it and permit its mouth to be hammered Without causing the material to spht or break.

Other objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the accompanying draw1ngs:-

Figure 1 is a sectional view through a device constructed in accordance with my 1nvention disposed in operative position in relation to the roof and soil pipe passing therethrough Figure 2 is a side elevation of the device alone, partly broken away and shown in section;

A Figure 3 is a view on the line 3-3 of Figure 2 previous to the conjoining of the flange and collar; and 7 Figures 4 and 5 are elevation views showing graphically the adaptability of the device to pipes passing through roofs of dilferent pitches.

Like reference characters designate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, A designates the roof of a building provided with an opening B through which the soil pipe C passes.

The device forming the feature of this invention is adapted to be applied about the pipe as shown in Figure 1 so as to effectively seal the roof against leakage at this point.

Numerous devices for thls purpose have heretofore'been proposed but in the majority of instances the articles have been made up of separable parts which require assembling on the job, soldering together, packingor calking, and other Operations which deprive them of the advantages of quick and ready application andpermit of leakage unless the 1 assembling is carefully carried out.

My device, on the other hand,isdesigncd as a unit or integral structure and as depicted in the drawing comprises a flange or plate 1 of suitable metal such as sheet copper, galvanized sheet iron or sheet lead, having an orifice 2 therein and a collar member surrounding said orifice. This collar is of ductile material such as lead, preferably molded in such configuration as to provide a reinforcing head at around the top, a corresponding bead 5 at the base, and connecting ribs 6, these tending to strengthen the collar against fracture when hammered into cooperation with the pipe, as later referred to. The collar is also formed in this molding operation with a depending lip 01' flange 7 at its base and with a groove 8 in the bottom of the head 5 to receive the upturned flange 9 formed about the orifice 2 of the plate 1. These two parts are joined together by seating the flange 9 in the groove 8 and bending outwardly the lip 7 against the bottom of the plate, such operation being preferably performed by suitable pressure apparatus, so as to insure the formation of a solderless leak-proofjoint at this point. It

is contemplated that the'groove 8 shall beslightly smaller than the flange sothat in the pressing operationthis flange will be forced into the metal to a certain extent and insure the character of joint above referred The unit thus formed is placed over the pipe and the collarhammered about the bead L until snug contact is made with the pipe all about the same, the extent of deformation of the collar by this process depending upon the pitch of the roof. It will be noted that the walls of the collar are normally angularly related to the plate 1, the opening at the top of said collar being truly circular while the opening at the base is relatively larger and ellipsoidal. This enables the device to be universal in application to varying pitched roofs and standardized for different diameters of pipes. Owing to the construction of the unit it may be inexpensively manufactured which is of wardly, and means extending from said edge to the plate for reinforcing the collar at the intern'iediate portion against fracture when forcing the edge inwardly as aforesaid.

2. As a new article of manufacture, an adjustable roof flange comprising a flange plate having an orifice therein and a collar of ductile material interlocking with the v edge of the orifice and formed with spaced annular and cross reinforcing heads.

3. As a new article of manufacture, an ad justable roof flange comprising a collar having exterior top and bottom reinforcing beads connected by intermediate ribs and formed at its base with an annular vertically extending groove in the bottom bead and a flange plate having interlocking means seated in said groove to provide a leak-proof joint in the plane of the plate.

4. As a new article of manufacture, an adjustable roof flange eon'iprising a collar having spaced annular beads and cross ribs and formed at its base with a groove and an adjacent bendable flange, a flange plate having an orifice therein the edge of which is upturned to provide a flange seated in said groove, the bendable flange on the collar coacting with the plate at the opposite side of its flange and ell'ccting a n. interlock between the collar and the plate to provide a leak-proof joint.

5. As a new article of mainlfacturc, a roof flange comprising a collar of ductile material molded with reinforcing heads at the top, bottom and sides, a flange plate having an orifice therein, the edge of the orifice being flanged to coact with the base of the collar and pressed into the material of the same to form a leak-proof joint around the orifice.

In testimony whereof I ailix my signature.

DAVID WEINBERG.
